A class diagram describing muon reconstruction packages ( muo_data, muo_hitreco, muo_segmentreco, muo_trackreco ) could be found here .
The description below includes links to the code contained in this package.
The purpose of muo_segmentreco package is reconstruction of track segments in the D0 muon system.
The physical components include:
This package depends on the following external packages:
The classes defined in the above components are described below. Each class is defined in a component of the same name unless otherwise indicated. The descriptions are brief. See the header files for details.
Abstract class for different segment finding algorithms. An engine for muon segment finding.
Combinatorial track finding algorithm. It is called if RCP parameter SegmentAlgorithm = "Combinatorial"
Implemantation of muo_dataprocessor interface to segment finding algorithm.
Framework Package for segment finding. Could call different algorithms, as defined by RCP parameters.
Persistent version of MuoSegment .
Chunk with muon segments.
Utility class describing muon hit in the local coordinate system ( X - perpendicular to wire plane, Y - in wire plane, perpendicular to wires, Z - in axial direction ).
Utility class containing information about muon segment in local coordinate system.
Global to local coordinate transformations for different parts of muon system. These transformations does not take into account small tilts. They just re-define X, Y, Z axes.
